  Cold work - Wikipedia, the free encyclopedia
Cold Work is a quality imparted on a material as a result of plastic deformation.
Upon examination, a material that has a certain amount of cold work possesses a higher yield strength and ductility of the material is decreased.
Cold work occurs as a consequence of plastic deformation.

 Cold fusion - Wikipedia, the free encyclopedia
Cold fusion is a name for any nuclear fusion reaction that occurs well below the temperature required for thermonuclear reactions (which occur at millions of degrees Celsius).
The term "cold fusion" was coined by Dr Paul Palmer of Brigham Young University in 1986 in an investigation of "geo-fusion", or the possible existence of fusion in a planetary core.
Although there may be a genuine physical phenomenon at work, the theory that it involves nuclear fusion is unproven and widely seen as unlikely.

It is important to note that there is no "inventor of the telephone." The modern telephone is the result of work done by many hands, all worthy of recognition of their addition to the field.
He began his researches in 1874 with a musical telegraph, in which he employed a make-break circuit driven by a vibrating iron reed which created interrupted current to vibrate the receiver, which consisted of an electro-magnet causing an iron reed or tongue to vibrate, exactly the same as Bourseul, Reis and Gray.
Working from the analogy of the phonautograph, Bell devised a receiver, consisting of a stretched diaphragm or drum of goldbeater's skin with an armature of magnetised iron attached to its middle, and free to vibrate in front of the pole of an electromagnet in circuit with the line.

 Cold War ideology doesn't work
At the root of the cold warrior worldview is the belief that everybody everywhere wants free markets and liberal democracy.
In 1992 Francis Fukuyama, in "The End of History," smugly hailed the end of the Cold War as the final victory of the "worldwide liberal revolution." He did not explore the problems of establishing liberal democracy in developing societies.
The West's victory in the Cold War encouraged a crude anti-statism that needs to be challenged if the United States is to avoid further disaster.

 Patent 4770719: Method of manufacturing a low yield ratio high-strength steel sheet having good ductility and ...
The annealing is performed after the cold rolling of a steel sheet with a chemical composition adjusted by positive addition of P (which has been extremely restricted in use owing to the promotion of brittleness), as a cheap strengthening element.
According to the method of Japanese Patent laid open No. 50-23,316, a high-yield point steel sheet is obtained by the continuous annealing and overaging treatment and is a solid-solution strengthened steel composed of ferrite and carbide, which is different from the method of the invention in that no overaging is performed after the continuous annealing.
A cold rolled steel sheet with a thickness of 0.8 mm having a varied P content in the chemical composition shown in Table 1 was subjected to three different annealing treatments, i.e.

 Heat Treatment of Low-Alloy Cold-Work and Hot-Work Tool Steels   (Site not responding. Last check: 2007-10-03)
Some typical applications are dies for tableware, shear blades for heavy plate and dies for plastic moulds, which requires steel possessing a high degree of dimensional stability and excellent polishability.
If a plate of increasing thickness is being punched and consequently the thickness measurement of the plate is approaching the diameter of the hole, the punches used show an increasing tendency to break if they are made from, for example, grades O1, A2 or D2.
Owing to its high toughness in comparatively large dimensions, grade S1 can successfully be used for tableware dies, which, depending on their dimensions should either be quenched in oil or be heat treated according to the combined oil-water quenching procedure.

If all areas where cold work tools are used, such as automotive, paper and pulp, general machining etc., the automotive industry amount to 40% of the total usage and is by far the largest segment.
The biggest problem with cold work is abrasive wear (scratching particles) and adhesive wear (micro-welds).
The steels for cold work have a high carbon content and can be hardened to a very high hardness and as the alloy content and hardness goes up the machinability goes down, which will be explained in the machinability section in this chapter.

 "COLD READS" & MORE: HOW MEDIUMS WORK
Mediums (and evangelists with working with ailments that need to be healed) have also been known to use sealed envelopes that contain questions for the spirits to answer.
Another popular variation on the cold read (and one that often does not make the final television cut) is the method that some mediums have of "brow beating" the sitter and refusing to accept the negative responses to their statements.
There are many clever ways to get this to work such as using different methods to probe for information, laughing away mistakes, getting around long pauses when the sitter fails to volunteer information and even blaming errors on "poor reception from the spirit world".
